CPVC Pipe pressure

The suppression of CPVC is a high-performance plastic pipe widely used in the food industry, automotive industry, electronics, water supply, chemical industry and construction industry. These pipes made of chlorinated polyvinyl chloride (CPVC) are resistant to corrosion that are resistant to high -temperature, resistant to acid and alkalis and can work stably at a temperature of up to 93 ° C. CPVC pipes are low to fluid and can increase the overall efficiency of the system. They meet several international standards for ensuring security and reliability. $ Dollar

CPVC Pipe pressure Industry knowledge

Key points CPVC pipe pressure Installation and welding technology: Avoid general construction defects

CPVC (chlorinated polyvinyl chloride) is widely used in many industries, including CPVC tubular pipe, drinking water CPVC, industrial water treatment, industrial wastewater CPVC, etc., from its excellent corrosion stability, high temperature stability (up to 90 ° C) and safety and sanitary performance. Nevertheless, incorrect installation and welding can lead to problems such as leak and decrease in strength. Below are key construction points and precautions in industry applications:

1. Material of preliminary processing and storage
Dry and clean: before welding, the surface of the CPVC pipe should be free from oil and dust, especially when using a high point of view in the industry, such as the CPVC electronic semiconductor pipe and a CPVC medicine to avoid pollution.
Avoid the effects of the sun. Long -term ultraviolet radiation will reduce CPVC strength, and measures from the sunny step should be taken in external applications such as the CPVC photoelectric pipe.

2. Cutting and accumulation
Use special cutting tools: make sure that the cutter is smooth to prevent gaps during welding.
Fighting: Especially when using CPVC in drinking water systems, bacteria can dilute bacteria or affect the flow.

3. Key technologies for welding solvent
Use special glue for CPVC: regular PVC glue is not suitable and can lead to insufficient read welding.
Apply evenly: apply the nest and flavor quickly and evenly to avoid the accumulation of glue or insufficient glue.
Do not rotate after the insert: rotation will lead to an uneven distribution of glue and affects the seal, which is especially important in high -pressure systems, such as CPVC nuclear energy.

4. Thermal expansion and support design
Consider the thermal lengthening: CPVC has a high thermal expansion coefficient, and the extension joints or flexible joints should be reserved in high -temperature media, such as CPVC pipes.
Reasonable support settings: Avoid the sagging of pipes, especially when transporting industrial wastewater CPVC over long distances.

5. Verification of pressure and acceptance
24-hour pressure test: make sure that the leak, especially the CPVC drinking water system, must comply with hygiene standards.
Avoid a sudden increase in pressure: gradually increase pressure to prevent the gap of the weld, if it is not completely cured.

Special requirements for the industry
The high purity industry (such as electronics and medicine): after installation, ultrapiral flushing of the water is required to ensure the absence of a residual solvent.
Corrosion media (such as industrial wastewater and metallurgy): Select CPVC pipes with higher pressure ratings and regularly check the aging of welded ears. . $
